It is essential but difficult to provide explanations that are both
correct and intelligible to
those who support GR research, e.g.the general public and their
representatives. Saulson offered two such explanations of how LIGO's interferometer is to detect
gravity wave -- a heuristic, mostly correct, explanation and a
more elaborate one that is always correct.

What does
the calculation mean?
1) Do gravity waves move the test masses?
2) Do gravity waves stretch light waves?
3) If so, how can you use light waves to detect gravity waves?

pg. 6 Answers:
1) It depends on your
coordinates.
2) Again, yes and
no.
3) Light is a rubber ruler
participating in the distortions being measured, but it is not a
static ruler and over the time it travels through an interferometer arm
there is a response that builds to the size found with the heuristic
calculation. It will work.
